Abstract: Abstract of the Disclosure A firebox has a liquid or gaseous burner and also a solid fuel grate assembly associated with a solid fuel inlet above the grate assembly for dropping solid fuel particles thereon.  The grate assembly includes upper and lower bar type members and an intermediate member of expanded metal.  A blower is mounted under the grate assembly and in combination with the latter provides an even pressurized draft for burning solid fuel particles.          A sweeping bar on side runs is capable of sweeping clinkers and ashes from the grate assembly.  A bottom auger receives the clinkers and ashes and carries them out of the firebox. forced air inlet directs a flow of air down on the solid fuel inlet to prevent combustion gases from traveling re-versely through the solid fuel inlet.  A heat exchange chamber includes a plurality of reversely turned tubes arranged in a plurality of paths and connected by end housings capable of removal for inspection and cleaning.          The solid fuel is fed to the furnace by a metering unit for use in combination with blowers to achieve maximum efficiency of the furnace.

Abstract: ABSTRACT OF THE DISCLOSURE         A roll-off hoist is mounted onto a vehicle to swing about a pivot at the aft end of the vehicle while the hoist moves along a slide plate supported by the pivot.  A piston and cylinder assembly is coupled between the slide plate and the aft end of the hoist rails.  As the hoist rails jut from the rear of the vehicle chassis, other piston and cylinder assemblies cause the forward portion of the hoist rails to swing above the chassis.  The aft end portion of the hoist rails descends to ground level to receive the forward portion of a roll-off container which is drawn onto the hoist rails by a powerful winch.  The piston and cylinder assemblies connected to the forward portion of the hoist rails are used to swing the hoist rails about the pivot while the piston and cylinder assembly in the rear portion of the hoist rails is inoperative to thereby elevate a container with the forward portion thereof extending high above ground level for dumping material in the container form an opening at the aft portion thereof.

Abstract: Title:  METHOD OF PROTECTING OFFSHORE         STRUCTURES AGAINST ICEBERG IMPACTS               Inventor:  STIG BERNANDER                 ABSTRACT OF THE DISCLOSURE         The invention relates to a method for protec-ting offshore structures such as oil platforms against impacts from icebergs by attenuating the impact energy of the icebergs.   Attentuation of the iceberg's energy is achieved  through  the  use  of  cables,  chains  or  other flexible  tension members which are  attached to energy absorbing  devices  on  the  structure.   The  cables  are disposed around the structure to be protected, with one end anchored on the seabed and the other end attached to the  structure  via  the  energy  absorbing  device.   The impact of an iceberg against the cables causes movement in  the  energy  absorption  device  and,  consequently, elongation  of  the  cables  under  tension.    The  energy absorbed  in this manner brings the  iceberg to a stop considerably more slowly than would be possible if one were relying on crushing of the  ice mass alone.   The stopping force is thereby reduced and so, consequently, is  the  structural  strength  required  of  the  offshore installation.

Abstract: ABSTRACT OF THE DISCLOSURE             This relates to a can, preferably formed of aluminum, which may be formed by a drawing process and which is so constructed wherein it may utilize wall thick-nesses less than those which are presently commercially permissible so as to be suitable for the packaging of food products and the like which are either hot filled or subject to retorting and still commercially compete with three-piece steel cans.  A primary feature of the can is the elimination of the customary double seam securing the end unit to the can body and replacing the same with telescoping of portions of the can body and end unit and providing an adhesive bond there between with the adhesive bond being enhanced by the reaction of the can body and end unit under conditions of internal pressure and internal vacuum due to the radial compression of the adhesive forming the adhesive bond to increase the shear strength of the adhesive.  The end unit is provided with a securing flange which is connected to the end panel by a corner defining a line of weakness wherein the securing flange may be torn from the end panel and at the same time peeled from the can body.  This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is directed to an acousto-optic dispersive light analyzer (AODLF) which is an electronically adjustable spectroscopic device capable of instantaneously monitoring many wavelengths with a fixed drive frequency. The AODLF has about a one octave range, whose center is selected by changing the RF.  The resolution of the AODLF in the infrared is several thousand, and it is electronically adjustable.  The acousto-optic device according to this invention is particularly useful for the detection and analysis of short light pulses.  An additional capability of the AODLF is its operation in a derivative mode for enhanced SNR of co-herence detection in the presence of a high incoherent back-ground by imposing a very small frequency modulation on the RF applied to the AODLF.  Then by phase locking each of the detector element signals at first the fundamental and then the first harmonic of the FM, the first and second spectrum derivatives of each resolution element can be observed.
